.COMBINATION CHAIR.

ipplicationiled September 15,y 1921.

. To aZZ whom it may concern specification.

The .primary-object of the-invention is the provision ofa `combination chair and Y stepladder,l lserviceable .as a rcomfortable .'*chair and readily convertible '.into a threestep laddenwherebyjthe devicemay .be used as a str-engandvsafeestepladder.

`A -further (')bjecttof the invention. is the =provision of a chair havingstep portions provided in theseat and .back thereof, adapted for ready shifting for. use Aas a step- 1ladder, thearrangement being 4such as to lockthe steps intheir shifted positions.

A still further objectof the invention .is

to providel a stepladder, chair that is simple andstrong inv construction,easy and inex- .pensive to manufacture and at ythe same time, is fullyserviceable as a chair when desired and readily changedto a stepladder j whenever theoccasion requires.

With these generalv objects in view,.the invention consists y1n the novel combination and arrangement of parts hereinafter more fully described in connection withthe .accompanying drawing and in which like reference characters designate correspondingparts' throughout the several views.

lIn the drawing, v

Figure 1 is a front elevation of the invention,

Figure 2 is a side elevation thereof illustrating by dotted lines thek position of the parts when the device is employed as a stepladder,

Figure 3 is a transverse sectional view upon line 3-3 of Figure 2, and

.Figure 4 is a-perspective view of a portion ofthe transverse brace.

Referringmore in detail to the drawing, my .invention broadlyconsists Ofa stand- -ard chair of substantially the usual form with frontlegs 10 and opposite side rails 11 .for connecting'the upper ends of the .legs 10 withflthe rear legs 12 as at 13, the

rear legs being extended upwardly forming sides 14 for the back of the chair. The chair bottom consists oftwoparts .15 and 16,`.the..part.:15.being permanently secured between'the rails "11 forming the rear por- Serial No. 500,758.

tion of the seat adjacent said sides 14. The

.bottom portion 16 is hinged as at 17 to the ksection 16 is swung upon its hinges 17 for alining flatly upon the bottom portion 15 as lllustrated by dotted lines in Figure 2.

Lower side rails 2O between the legs 10 and 12 beneath the upper rails 11 have a lower step 21 mounted thereon'between the front legs 10 and directly beneath the opening formed by the bottom portion 16 when in its shifted turned-.back position. The forward ends of the lower rails 2O preferably project forwardly of the front legs 10 with the forward edge of the step 21 correspending to the end facesof lsaid rails 20. A suitable bar or connecting round 22 ispositioned between the upper ends of the sides 14 in the usual manner. A connecting brace 23 is secured between thesides 14 beneath the rod 22 by upturned angular ends 24 fastened by means of screws or other similar devices 25 to the rear edge of the sides 14. An upper step 24 is pivoted by means of trunnions 25 between the opposite sides 14 in a position for engaging the horizontal flat connecting brace 23 when said upper step 24 is swung tov its horizontal position in the stepladder arrangement of the device as illust-rated by dotted lines in Figure 2 of the drawing.

Rods 26 are pivotally connected between the forward bottom portion 16 and the upper step 24, such connection insuring the substantially` vertical position of the upper ystep 24 between the sides 14 and constitut- `upper step 24, with therods 26 voutwardly of the sides 14.

Referring more in detail to the drawings, the formation of the chair with its movable parts will be fully understood from the foregoing description as well as the manner of moving the bottom portion 16 upon its hinges 17 to automatically shift the combined back panel and upper step 24 to its flat horizontal position for use as a step as illustrated by dotted lines in Figure 2. The pivot points 27 are so positioned upon the chair bottom member 16 with respect to the hinge 17 as to be brought off-center when the portion 16 is turned backl with the upper step 211 horizontal which results in locking the upper step 211 in position flatly engaging the bottom of the brace 23 so that the weight of a person upon the upper step 24 will be partly borne by the brace 23 and the step 24 prevented from' pivoting upon the trunnions 25 by reason of said locking position of the rods 26. The opening in the chair bottom caused by rearwardly shifting the portion 16 permits a person to readily mount upon the lower step 21, then upon the rearwardly turned bottom portion 16 as a second or intermediate step and -then upon the upper horizontal step 211. By returning the panel portion 16 to its normal place in said formation, the rods 26 automatically bring the upper step 24 into its position as a back panel engaging the forward edge 30 of the brace 23 as shown in Figure 1.

'While the form of the invention herein set forth is believed preferable, it will nevertheless be understood that minorchanges may be made therein without departing from the spirit and scope of the invention.

What is claimed as new is:

y 1. A stepladder chair comprising forward and rear legs, upper and lower connecting braces therefor, a' lower step secured to the lower braces between said front legs and projecting forwardly thereof, a two-part seat for the chair carried by said -upper braces,`hinge connections vbetween the forward part of said seat and said upperrails whereby an interrupted portion is adapted to be formed in the seat for permittinguse of said lower step, the hinged seat portion being adapted for rearward swinging movement for use as a second step, opposite sides for the chair back at the upper ends of the rear legs, a combined upper step and back panel pivoted between saidV sides above the seat and link connections between said panel and the hinged seat section to cause both of the same to assume their chair or stepladder formation at will, the'point of connection between the link and hinged seat and panel sections, being respectively, forwardly of the hinged seat section and below the pivot of the panel section for holding the seat and panel sections in locked'position when swung rearwardly, with said j l sections being simultaneously shifted by the link connection.

2. A stepladder chair comprisingforward kand rear legs, upper and lower Vconnecting panelpivoted betweensaid sides Vabove the seat, al brace between said sides adapted for seating engagement with said panel when in either its step or back forming positionand link connections between said upper step and hinged seat portion adapted 4f or the simultaneous shiftingy thereof 'at' will,y :the point of connection between the link and hinged seatv and panel sections, being respectively, forwardly of the hinged seat s eCtQn and below the pivot of the panel section for i.

holding` the seat and panel sections invlocked position when swung rearwardly, withy said sections being simultaneously shiftedby the link connection.` 4

3. A stepladd'er chair comprising forward and rear legs, upper andlower connecting braces therefor, a lower *step secured'to vthe lower braces between saidfront legsv and projecting forwardly thereof, al two-part seat for the chair carried by said. upper,"

braces, hingel connections between the 'forward part of said seat and said upper rails whereby an interrupted portion is adapted to be formed in the seat for permitting use of said lower step, the hinged ,seatlportion l being adapted for Arearward vswinging move- `ment for use as a second step, opposite sides' for the chair back at ythe upper ends of the rear legs, a combined upper step and back panel pivot-ed between said sidesabove the.,A seat, opposite links pivotally connected out-A wardly of said sides between the upper-step and the hinged seat portion whereby'y the upper step is locked horizontally when the seat portion is in its rearwardlyswung position-`v horizontally in ladder formation,`r the point of. connection between ther link and hinged seat and panel sections, being respectively, forwardlyv of the hinged seat vsection and below the pivot ofthe panelfsection for, holding the vseat and panel sections in locked position when swung rearwardly, with `said sections beingsimultaneously Vshifted by they link connection.
